If you are using one of the default email templates, the form field name is used in the email. If you want to display the name you want for the field, I would recommend unchecking the Create a file for your email checkbox and clicking on either the edit with the pencil next to it or the edit with the DW icon next to it. If you edit with the pencil box, an edit window will pop up and you will be able to type in the text you want displayed, such as Name: and then click on the lightning bolt icon in the bottom right of the window. From here there is an entry for your form (the form name). You would want to expand that and select the form field you want displayed and hit ok.
If you edit using dreamweaver, a file will open in dreamweaver where you can make the edits. To add the form field values, you would go to the bindings panel and find the form entry and drag the form field to where you want the value displayed.
